Letters Patent No. 109,522, dated November 22, 1870.

IMPROVEMENT IN GRAINREGISTERS.

The Schedule referred to in these .Letters Patent and making part of the same.

To all whom lit may concern Be it known that I, CHRLESLAMB, ofthe city of Binghamton, in the county of Broome and. State of New York, have invented certain new and useful Improvements in Grain-Measurers; and I do hereby declare that the following is a full, clear, and .exact description thereof, reference being had to the accompanying dra-win g and to the letters of reference marked thereon which form a part of this specification.

The nature of my` im'entioncousists in the construction and arrangement of a self-emptying grainmeter,77 as will be hereinafter fully set forth.

In order to enable others skilled in the art to which my invention appcrtainsto make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a longitudinal vertical section, and

Figure 2 is a plan view of my machine.

A represents a circular box, of any desireddimensions, resting upon legs, B B, a suitable height from `theioor, and having around opening, (t, in its bottom, near oueside.

From this opening a tube, C, leads downward for a short distance, to the lower end of which tube the sack which is to be filled with grain is fastened.

Wit-hin the box A, upon its bottom, is placed another circular box, D, which just ts within the rim of the box A, and upon the bottom ot' which are secured, near the outer edge, four half-bushel measures, E E, atequal distances apart.

The bottom of the box D is provided with an opening under each measure E ofthe same size as the lowerend of the measure, and in said opening is hingcda valve, b, of suitable size to close up the said' opening and form the bottom of the measure.

On the opposite side of the box A from the tube C is attached a register, consisting of a casing, G, with a vertical shaft, d, through the center.

Near the lower end of' this shaft is secured a cogged or toothed wheel, H, and the upper end of the shaft d passes through a dial-plate, I, and is, above the same,

provided. with a inger or indicator, e, the dial I being numbered to correspond with the number of cogs-or teeth on the wheel H.

"On the outside of the rim of the box D, direct-ly opposite each other, are placed two pins, t t', which, as the box D revolves, move in a groove on the inside of the rim of the box A, except at the point where the indicator or register is attached. Y Here a small opening is made for a portion of the wheel H to project through, so that the pin/i can strike the same and turn it the distance of one of its teeth or cogs. v y

On one side, at equal distance from the register and the tube C, a hopper, J, is attached to the box A, from which hopper a. spout, K, leads inward oven the rim of the box, and has a sliding door, f, at its outer end.

rlrhe operation of my machine is as follows:

The grain heilig poured -into the hopper is allowed to pass through the spout into one of the measures E. Then this is filled thodoor f in the spout is closed.

The box D is now revolved, when the filled measure first passes under an arm, L, so that the top is scraped ott' level, the grain that is scraped oil' the top falling into the box D, and passes out through a tube, It, in the center.

W hen the box D has completed a one-fourth revolu tion a spring-pin, h, attached to thel box A, passes into a hole in the rim of the box D and stops it.

The filled measure is then directly above the tube C,va nd the valve b falls down, emptying the grain.

l rllie next measure 1s under the spout li, being filled, and as soon as filled the spring-pin h is withdrawn and the box D-turned another one-fourth around, and the same operation continued.

There beingfonly two pins, li, to operate the indicator, it is evident that this will show two bushels vfor ycach revolution of the box D, the measures being halfvand for the purpose set forth.

In testimony that I claim the foregoing as my own, I affix my signature in presence of two witnesses.
